InstantGo is one of the smart features in Windows 8.1 that replaces the sleep/standby features. It was previously called Connected Standby in Windows 8 and Windows RT. InstantGo is not just a software feature, it works in conjunction with System on Chip (SoC) designs from both Intel and ARM. Microsoft today blogged about the InstantGo feature and the popular misconceptions about it. You can check whether your system supports InstantGo by typing powercfg /a in Commands prompt and press Enter, you’ll see the Standby (Connected) option only if you have InstantGo:
What is InstantGo?
InstantGo maintains network connectivity when your screen is off in standby mode, allowing the system to update things in the background, and keeping it ready to instantly resume. For example, it can sync your email while your screen is off so new mail is ready and waiting as soon as you come back. Or if you want to be reachable via Skype even when you step away from your PC, you can go ahead and turn the screen off, and your calls will still come through. Power consumption in this connected standby mode is very low, and yet the system is always ready to spring back to life with your next interaction.
